WASH Cluster – Water in Emergencies W W1 10 WASH Linkages Health Nutrition Logistics Shelter Protection Early recovery Water is life - without water, we dehydrate & die Hygiene is difficult without water, increasing diarrhoeal diseases PLWHA may have increased WASH needs Children who are malnourished are more susceptible to dying from diarrhoea People with diarrhoea cannot absorb the food they eat and hence this contributes to malnourishment Efficient logistics are essential for effective WASH programmes in emergencies – value your logistician! The siting of shelter and WASH facilities need to be coordinated effectively to enable equitable use and access Poorly sited WASH facilities, can lead to increased vulnerability and attacks on women or children including rape and can inhibit use Women and children who have to walk long distances for water can be vulnerable to attack Good WASH services at community level aids early recovery
